The XperienCentral Performance Dashboard provides detailed information about how the parts of XperienCentral's infrastructure are functioning. Because XperienCentral is a complex system, the interaction between many different sub-systems and configuration options has a direct impact on how it performs. Using the Performance Dashboard, system administrators, developers, and application managers can quickly identify problems and then make the necessary configuration changes to ensure that XperienCentral performs optimally. The Performance Dashboard measures the speed and response time of page requests and internal queries as well as other settings that affect how XperienCentral runs and rates the results according to the optimal expected results.

To enable/disable the XperienCentral debug options that affect performance, run the Web Manager Setup Tool. On the [General configuration] tab, navigate to the "Development_Settings". Clear the checkbox for "enable_debug_messages". Note: In a production environment, the setting "enable_view_resolve_cache" should be selected.

 

Setting the Log Level

The level at which you log messages has a direct effect on system performance. Each time a system event is logged, a small performance hit occurs. Logging messages of type SEVERE affects the system the least whereas logging at the INFO level can cause the system to slow down due to the sheer volume of messages that are written to the log. The effect that the logging level has on XperienCentral performance is indicated as follows.
